Testing Standard Sample Calibrating Device Developing of Entire Diameter Rock Gas Permeability and Its Calibrating Technique to Value Tracing to Source

• Abstract:

  Rock gas permeability is one of the most important foundation parameters during exploration and development of oil/gas fields. At present, only Ø 25 mm × 25 mm rock gas permeability testing standard material is produced and calibrated in China, the value tracing to the source and device calibration of other specification rock permeability devices are dependent on overseas, which seriously restricts the development of rock physical property testing technique. On the basis of deep analysis to calibrating technique of rock permeability testing device, this paper introduces the entire diameter rock permeability testing standard sample calibrating device from our own design and its calibrating technique to value tracing to source, which is a great breakthrough to calibrate big diameter rock gas permeability of various specifications using small diameter standard sample in China. The rock permeability calibrating device introduced in the paper granted the patent of invention in China, its calibrating method has been applied for the patent
